Table Band Saw for Metal: Types, Uses, and Selection Criteria
You need a table band saw for cutting metal and you want to know what to look for. A table band saw for metal is a stationary band saw with a table that supports the workpiece while cutting metal. You need to know the types, what to compare, and how to choose the right one.
A table band saw for metal is a stationary band saw designed for cutting metal bar stock, pipe, tubing, and structural shapes. The workpiece rests on a table and is fed into the blade. Table band saws for metal include vertical metal cutting saws and horizontal saws with a table attachment.
Types
Vertical Metal Cutting Band Saws
Saws where the blade runs vertically and the workpiece is fed into the blade on a table.
Features: Variable speed (40 to 1000 FPM), coolant system, heavy construction, cast iron table. Best for: Contour cutting, straight cutting, irregular shapes. Cost: 1000 to 10000 dollars.
Examples: DoAll, Wellsaw, Clausing, Dake, Baileigh.
Combination Wood/Metal Saws
Woodworking saws with variable speed that can be reduced for metal cutting.
Features: Variable speed, cast iron table, fence and miter gauge. Best for: Occasional metal cutting in a woodworking shop. Cost: 500 to 2000 dollars.
Important: Most woodworking saws run at 2500 to 3500 FPM, which is too fast for metal. Only use a woodworking saw for metal if it has variable speed that can be reduced to 40 to 500 FPM.
Horizontal Saws with Table Attachment
Horizontal metal cutting saws with a table that allows vertical cutting.
Features: The saw head can be locked in the vertical position, and the workpiece is fed into the blade on a table. Best for: Shops that need both horizontal and vertical cutting. Cost: 500 to 5000 dollars.
What to Compare
1. Cut Capacity
Round capacity: Maximum round stock diameter. Rectangular capacity: Maximum rectangular stock size. Throat: Maximum width of stock for vertical cutting.
2. Speed Control
Single speed: Not suitable for multiple materials. Multiple speed: Several fixed speeds. Variable speed: Continuously adjustable. Best for matching speed to material.
Recommended speeds:
- Mild steel: 60 to 200 FPM
- Stainless steel: 60 to 100 FPM
- Aluminum: 200 to 400 FPM
- Brass and copper: 100 to 200 FPM
3. Motor Power
Light use: 1/2 to 1 HP. Regular use: 1 to 2 HP. Heavy use: 2 to 5 HP.
4. Coolant System
Why it matters: Coolant extends blade life, improves cut quality, and clears chips. What to look for: Coolant tank, adjustable flow, nozzle position.
5. Table Size and Construction
Cast iron: Most rigid and stable. Steel: Good rigidity, lighter than cast iron. Table size: Should accommodate your workpiece. Table tilt: Some tables tilt for angle cuts.
6. Blade Guides
Carbide guides: Best, longest lasting. Bearing guides: Good. Roller guides: Acceptable for light use.
Blade Selection
Blade Material
Bi-metal M42: The standard for metal cutting. Cost: 15 to 35 dollars. Bi-metal M51: Harder edge for tough materials. Cost: 20 to 45 dollars. Carbide-tipped: Longest life for production. Cost: 50 to 150 dollars.
TPI Selection
| TPI | Best For | Material Thickness |
|---|---|---|
| 6 to 8 TPI | Thick solid bar | 1 to 4 inches |
| 10 TPI | General metal cutting | 1/4 to 2 inches |
| 14 TPI | Medium thickness | 1/8 to 1 inch |
| 18 TPI | Thin material | Under 1/4 inch |
| 10/14 variable pitch | Mixed thicknesses | All |
Blade Width for Contour Cutting
| Blade Width | Minimum Cut Radius |
|---|---|
| 1/8 inch | 5/16 inch |
| 1/4 inch | 7/8 inch |
| 3/8 inch | 1-1/2 inches |
Setup
1. Install the Blade
- Open the wheel covers.
- Release blade tension.
- Install the blade with teeth pointing down (toward the table).
- Apply tension.
- Check tracking.
- Close the wheel covers.
2. Set the Speed
- Determine the material and thickness.
- Look up the recommended speed.
- Set the speed using the variable speed control.
3. Adjust Blade Guides
- Set side guides about 1/32 inch from the blade.
- Set thrust bearing about 1/64 inch behind the blade.
- Set guide post height about 1/4 inch above the workpiece.
4. Set Up Coolant
- Fill the coolant tank.
- Position the nozzle at the blade-workpiece contact point.
- Turn on the pump and adjust flow.
FAQ
Can I use a woodworking band saw for cutting metal?
Only if it has variable speed that can be reduced to 40 to 500 FPM. Most woodworking saws run at 2500 to 3500 FPM, which is too fast for metal.
What is a table band saw for metal?
A stationary band saw with a table that supports the workpiece while cutting metal. Includes vertical metal cutting saws and combination wood/metal saws with variable speed.
What speed should I use for cutting steel on a table band saw?
60 to 200 FPM for mild steel. 60 to 100 FPM for stainless steel. Use the variable speed control to set the speed.
Do I need coolant for metal cutting on a table band saw?
Yes, for steel and stainless steel. Coolant extends blade life, improves cut quality, and clears chips. For aluminum, skip coolant.
